The dimensions of the ear differ in the whites, it was shown by 
Schwalbe, 1 with age, both the height and the breadth, but especially 
the former, increasing up to at least the 7Oth year of age. The 
module and ear index modify accordingly, the module increasing, the 
index decreasing; in the words of the just mentioned author, 2 "the 
ear in the aged is on the average absolutely longer and broader, but 
relatively narrower, than that in the young adult. The same condi- 
tions were found by the writer in the Indians, and they also exist 
among the Kharga Egyptians. As seen from the following table, the 
average height of the ear in the seventeen oldest men of the series is 
to that of the seventeen youngest adults as 109.9 to 100; the breadth 
is as 104.2 to 100; the module or mean diameter as 107.7 to 100; 
while the cephalic index is but as 94.6 to 100. We are dealing here 
evidently with morphological conditions of wide extension, in which 
racial or tribal differences are restricted to degree and other secon- 
dary features of the phenomena.
